fix: deploy blockers from red+scientist swarm review

Browse Source 
Blocking (would cause production incidents):
- env var prefix: LUX_* → LUXD_* (27 vars). Viper reads only LUXD_*;
  LUX_* silently ignored → node would start with default config on every env.
- admin API enabled + sybil disabled defaults: explicit LUXD_API_ADMIN_ENABLED=false
  and LUXD_SYBIL_PROTECTION_ENABLED=true in base ConfigMap.
- bootstrap peer config absent in new overlays: added LUXD_BOOTSTRAP_IPS /
  LUXD_BOOTSTRAP_IDS keys to base ConfigMap; overlays/operator populate per-env.

Defense-in-depth additions:
- ServiceAccount `luxd` with automountServiceAccountToken: false (no API access).
- PodDisruptionBudget maxUnavailable=1 (works at 5 → 100 validator scales).
- NetworkPolicy: ingress 9631/TCP from any (P2P), 9630/TCP cluster-only
  (HTTP), 9090/TCP monitoring-namespace only (metrics).
- podAntiAffinity preferredDuringScheduling by hostname — spread across nodes.
- updateStrategy: OnDelete — operator drains one pod at a time.
- podManagementPolicy: Parallel — validators start in any order.

Swarm verdict was NO-GO until these fixes. Addresses red critical #1 (admin
API), #2 (sybil), high #4 (gateway bypass via direct LB), medium #7 (no
NetworkPolicy/RBAC), and scientist blockers on env prefix + bootstrap.
